Hmm, that kinda sucks. I know with Pro you get something like 50 licenses and I am on a client site where I could potentially leverage that as a solution for their problems apps. Unfortunately the site is small and they only have Wise standard. Maybe they will spring for some SVS licenses but it is always easier to sell a solution you already own.

Here is the answer I got:
Only WPS Pro version enables for creating VSA packages, not WPS Std.

In order to encourage organizations to explore the use of SVS in their environments, WPS Pro comes bundled with 50 client licenses for SVS. This applies to new license sales only. Existing WPS Pro customers are able to purchase 50 SVS client licenses for every WPS Pro license that they own.

SVS licenses are NOT offered to WPS Standard customers, because WPS Standard does not include the tools required to create and manage .VSA packages.
